Abstract

In this study, a different Maximum Power Point Tracking (MPPT) technique to obtain maximum efficiency from wind turbines is mentioned. The system, which is experimentally established and tested, consists of a wind turbine emulator, which consists of asynchronous machines coupled to each other and one of them acts as the motor while the other is the generator, transformer, rectifier with high current, chopper, invertor, data acquisition card and computer unit, current and voltage sensors, loads and a fuzzy logic based MPPT software designed in MATLAB/Simulink environment. Maximum load to be fed in the case of existing environmental conditions can be defined by continuously calculating the maximum power value to be obtained from the wind by the computer. This system differs from the other studies in that it tracks maximum power point with only the current and voltage date of the system without taking wind power, pressure, heat, humidity etc into consideration; besides, the designed Fuzzy Logic Reasoning (FLR) can continuously calculate maximum power point by using this current and voltage data.
